Release Naming Conventions

BQN software release is identified by three digits (e.g., R4.1.1):

  • The first digit indicates a mayor release (e.g., Release 4). A major release requires new platform packages (normally it is not compatible with platform packages from previous major releases).
  • The second digit indicates a minor release within the major release (e.g., Release 4.1). Contains new functionality and it is compatible with the platform packages of its major release. Simply involves the installation of a BQN package.
  • The third digit is a patch number, delivering corrections of the minor release. This is the convention from R4.1 onwards (R4.0 was delivering also functionality using the third digit).
